The Lowdown
Alright, grab a coffee and pull up a chair. Rusty here, and I've got your 16-day look at the Basque coast. We're focusing on Tarnos - La Digue, and I gotta be straight with you: for the first week and a half, it's a tough watch. The ocean's just not dialled in.
We’ve got a real dry spell to start. From Friday the 17th right through to Sunday the 26th, the waves are small, weak, and messy. The wind is mostly onshore or cross-onshore, chopping everything up. The swell energy is pathetic, sitting in the low double digits, like 12 to 84 (weak). You'd be fighting a losing battle out there. The water temp is about what you'd expect for this time of year, so no excuses there. It's just flat and ugly.
Then, out of the blue, Monday the 27th of July shows a tiny glimmer. The morning goes glassy with a light offshore easterly breeze, cleaning up a weak 2 ft NW swell. The energy is still low at 71 (weak), but it's surfable. It's small, it's clean, and for a beginner, it might be a fun little session. The crowds are "sometimes" here, so you might have a few friends out, but it beats sitting on the beach.
Now, here's the standout. The real action is on Tuesday the 28th of July. The morning session is the pick of the entire forecast. We're looking at clean, glassy conditions with a light SSW breeze. The swell is a solid 3 ft from the NW, with a period of 10 seconds. That's a proper groundswell that will wrap in nicely. The combined energy jumps to 234 (moderate), so there's some punch. The offshore wind and glassy surface will make it clean and lined up. This is the one to point your board at. The afternoon sees a bit of a cross-shore breeze pick up, and the energy is higher but the quality drops, so hit it early.
Thursday the 30th of July also has a promising morning. Another glassy start with a NNE breeze, and a 4 ft NW swell with a 10-second period. The energy is up there at 341 (moderate). That's a proper morning session before the wind swings around.
The swell gets a bit bigger towards the end of the month – Friday the 31st of July sees a 6 ft NW swell, but it's got a cross-breeze and a shorter period, making it less appealing. The 6 ft is getting a bit big for the beginners, and the wind will make it lumpy for everyone else. The model is a bit uncertain this far out, but it's something to keep an eye on.
So, to wrap it up: the first 10 days are a write-off. Your best bet is the morning of Tuesday the 28th of July at Tarnos - La Digue for a clean, fun, glassy session. Thursday the 30th morning is a solid backup. Don't waste your energy on the rest.
Rusty, signing off.
